Hi all,
I put together a new build last week and ran into some problems with getting a video output to my display.
What is happening:
When I turn on my system I typically get something *trying* to display on my monitor, it turns on and off a few times, but eventually loops forever with nothing being displayed. When I remove my GPU and use my onboard graphics it consistently boots fine.
The WEIRDEST part of all of this, is that I have stepped away a few times to take a break and come back the next day, tried a new fix, and then got a clean boot with the GPU in. Naturally, I thought I solved my problem, put my case back together, and then tried to boot again, but it reverted to the exact same results as normal. This has happened only 2 times out of 100s of boot attempts, but both times being after a first try fix following a period of being away. Not sure if this could be because the PSU was unplugged/off and it's resetting and draining the CMOS completely in a way I hadn't replicated before? Or something else completely.. ?
Things I have done so far:
Because my system is able to boot fine using onboard graphics it really seems related to my GPU or possibly motherboard slot?
I am not sure what else to try other than fully replacing my motherboard at this point. Any ideas / suggestions are welcome!
Thanks so much in advance for your help. 🙏
System Specs:
CPU: Intel Core i7-12700K - Core i7 12th Gen Alder Lake 12-Core (8P+4E) 3.6 GHz LGA 1700

Things I have done so far:
- CMOS reset, including battery removal, holding power button down, waiting 5-10 min, and then replaced it
- Cleaned all dust and debris from original case
- Checked and inspected all connections, multiple times over on PSU, CPU, GPU
- Removed GPU completely = boots fine using onboard graphics
- Swapped out HDMI cable
- Swapped out 3 different GPUs of varying power levels
- Swapped out a new PSU
- Removed a piece of metal on my case that was close to the HDMI connector (was scared this could be touching the metal on HDMI plug and shorting it out)
- Reseated multiple GPUs many times
- My motherboard LEDs seem to illuminate differently depending on various changes I've made. When GPU is plugged in and display is looping, it is typically displaying the green LED (boot).
- Removed all RAM but 1 and reseated, double checked they are firmly in place
